STRAINER-SECTION FOR FLEXIBLE METALLIC PIPES.

Specification of Letters Patent.

Patented Mar. 14, 1911.

Application filed May 23, 1907. Serial No. 375,213.

TocZZ whom it may concern:

Be it known that I, LAMBERT J. Borne, a citizen of the United States ofAmerica, residing in the city and county of Philadelphia, in the Stateof Pennsylvania, have invented a certain new and useful Improvement inStrainer-Sections for Flexible Metallic Pipes, of which the following isa true and exact description, reference being had to the accompanyingdrawings, which form a part thereof.

My invention relates to jointed flexible metallic pipes especiallyadapted and intended for use in coupling pipes carried by an engine andits tender or by coupling cars, my object being to provide in such orsimilar pipes a section adapted to include and inclose a strainer 'in acompact and effective manner.

The nature of my invention will be best understood as described inconnection with the drawings in which it is illustrated and in which.

Figure 1 is a side elevation of the flexi- ,le metallic pipe describedin my former application and Fig. 2 is a section on the line 22 of Fig.1, illustrating the special strainer section which constitutes thesubject matter. of my present application.

. It will be understood that any elbow sec tion of the flexible pipe canbe utilized as the strainer section.

In the drawing, A, A, indicate the ends of the train pipe, B,'B; C, C,and F, F", be ing the elbow sections utilized in the makeup of theflexible pipe. The elbow sections D, F, and D, F, are shown as connectedby straight pipe sections E, E.

G, G; G G G G and G3 are the joints by which two abutting elbow sectionsform a swivel jointwith each other, the swivel joints beingpreferablymade up as shown in Fig. 2, one elbow section having anextension H, formed. with a groove "H in which groove is sprung ametallic ring J. A sleeve section I, of theadjacentelbow fits over-theextension II, abutting against the ring J, and having an extension I",projecting beyond the ring to receive the metallic packing rings K,which are clamped in place against the ring J, by the clamp ring L,

screwing on the threaded outer surface I and held in place by a jam-nutL For the purpose of adaptingit to receive a strainer I form the elbowsection F with an annular seat M, and an oppositely disposed opening Mof sutiicient size to admit the strainensaid opening being closed by acap M N is the strainer, having a beaded end N, which fits on the seatM, and an outer end N against. which the cap M presses when screwed toplace as shown in Fig. 2.

It will be obvious that by the simple construction I have described, Ican include a strainer in any one of the elbow ,sections of my flexiblepipe or of pipes having similar constructive features.

The construction is very compact, while at the same time the area of thestrainer surface is relatively large. A removable cap M surrounds andsecurely holds the small end of the conical strainer N in place,

while at the same time the cap M may be of the same diameter or of butslightly larger diameter than the large end of the strainer N.

Having now described my invention, what I claim as new and desire tosecure by Letters Patent is,

An elbow pipe section adapted to form part of a jointed flexiblemetallic pipe and having an, internal'seat surroundingt e passagethrough the elbow adjacent one end thereof, and an internally threadedopening M in line with said seat and at the bend of the elbow, incombination with a ca) adapted to be threaded into and close sai openingand internally hollowed, and a strainer in the form of a hollowtruncated cone,- the base of which seats against said seat while thesmaller end extends into said hollow cap, thelparts being soproportioned 'that the intern 1 diameter of said opening M is notmaterially greater than the maximum external diameter of the strainerwhile the portion of the strainer entering said hollow cap is separatedfrom the surround ing porti0n of the hollow cap by a space.
